Using Pythagoras theorem:-
10^2 = 4^2 + h^2
h^2 = 100 - 16 = 84
h = sqrt 84 = 9.17 ft answer
#3 sin(x) = -sqrt(2)/2 so x = 315 degrees. So we have sin(x+pi/3) = sin(375) = sin(15) which in exact form would be (sqrt(3) -1)/(2sqrt(2))
#4 to find x we take the arctan(20/21) which is approximately 43.6 degrees and add 180 to it since it's in the 3rd quadrant which is 223.6 degrees so we do sin(223.6 + 90) = sin(313.6) which equals -21/29. This can also be done with the pythagorean theorem. -21/29.
#5 13^2 - 5^2 = 12^2. so sin is -12/-13 = 12/13. we take arcsin of that and add 180 and then divide by 2 and take the sin of that and its approximately 3/sqrt(13).
#6 sin is 4/5 so we take arcsin of that and get 143.13 which -60 is 83.13 and we take the sin of that to get 3/10 + 2sqrt(3)/5
Hope this helped :L
Answer:
The question is lacking the detail of the price of the ice cream cones.
Assuming the ice cream cones cost $2 each then she would have to sell;
= 250/2
= 125 ice cream cones
<em>If she sells 125 ice cream cones, she will be able to raise $250 if the cones are sold at $2 each. </em>
